British men are dangerously ignorant of the prostate gland, according to a men's health charity.
It is crucial for sex as it produces semen and helps with ejaculation. It can also affect urination.
But it is also the leading cause of cancer in men, with 40,000 diagnosed each year, Prostate Cancer UK says.
A survey by the charity showed nearly one in five men did not even know they had a prostate and men were "blind" to the risk of cancer.
